MTV News has of course been tracking the release of her record, which finally dropped on Tuesday, but we were also on hand as [article id="1660729"]she performed in Las Vegas[/article] at the Palms' Rain nightclub. Fans will get to see the show — and much more — for themselves when the special airs on Sunday, April 3, at 9 p.m. ET on MTV.

When we spoke to Spears' longtime manager, Larry Rudolph, in Vegas, he told us Brit wanted to put on a spectacle for her fans. She wanted to take her first Femme Fatale live [article id="1660787"]performance to Vegas[/article] because much like the city, Spears' concerts have lots of sparkle, pyro and razzmatazz, he explained.

"We chose this place; we chose the Palms because the Palms is where Britney has so much history," he said. "We performed here with the Britney album, we did a similar thing. We're doing this eight years later now and we're doing it for the fans."

Rudolph stressed that Spears has one main goal: to entertain her fans in the Femme Fatale era. "For her, it was really important to do it for the fans the first time she was out there," he explained. "To do it here in Las Vegas, where everything is bigger and everything is more exciting and the fans are here for her, this was the place to do it.

"I want them to know — when the fans watch this — I want them to know that Britney is back and better than ever, not that she's ever gone anywhere," he continued. "But she's back and she's better than ever."
